Question

Why does water form a spherical shape when we used to drop water up or throw water around?

Solution

Water:

  • Water (H2O) is an inorganic, transparent, tasteless, odorless, and almost colorless chemical substance.
  • It is the major ingredient of the earth's hydrosphere as well as the fluids of all known living species (in which it acts as a solvent).

Surface tension:

  • Surface tension is caused by the cohesive interactions of liquid molecules.
  • The molecules in the liquid's bulk have neighboring molecules on either side.
  • Molecules are tugging on each other in all directions equally, resulting in a net force of zero.

The spherical shape of water:

  • Because of a phenomenon known as surface tension, water drops, or any other liquid's drops, are spherical in shape.
  • This acts on the surface of a freely falling drop in a liquid to reduce its area.
  • In comparison to other things, such as an ellipsoid (an egg-shaped object), the ratio of surface area to volume in the case of a sphere is the smallest.
  • Spherical shapes have less potential because they can withstand any external force in the atmosphere.
  • Water forms a spherical shape because of its surface tension.
